Second, the response to DDoS attacks: (including the above settings)

This article introduces the PHP implementation of malicious DDoS attacks to avoid the bandwidth consumption problem method, this article is a simple method, the need for friends can refer to the
DDoS attacks implemented using PHP code can cause bandwidth to be consumed and become card B.
The approach is:

When you open a program, select the first social-engineering attacks, a social engineering attack method, can include several attack methods
1. Harpoon-type fishing attack
DDoS attacks: A distributed Denial of service attack is the use of large numbers of chickens or forged IP, the launch of a large number of server requests, and finally lead to server paralysis attacks. CC attack: Similar to a DDoS attack, but it is characterized primarily by
connection request cannot be appropriate. The attack initiator's resource consumption is negligible.Ii. how to defend against SYN flood attackLet's take a look at the types of SYN flood, as shown in:1. Direct Attack Attackers use a fixed source address to initiate an attack, which minimizes the cost to the attacker2. Spoofing
.qq.com Web page. This trust-domain security method for fast login Plug-ins is meant to prevent web pages from other unsecured domains from invoking the plugin, while the developer writes the Cross-domain settings of document.domain= ' qq.com ' on a page in xui.ptlogin2.qq.com. As a result, this trusting domain is in no shape. Through the QQ arbitrary station of an XSS vulnerability we can attack xui.ptlogi
ARP spoofing/attack repeated attacks, is the recent network industry generally understand the phenomenon, with the escalating ARP attacks, the different solutions in the market spread. But the author recently found that some programs, in the short term seems to be effective, in fact, the real ARP attack can not play a role, but also reduce the efficiency of the LAN.
Multi-user response said that some ARP c
PHP through the session anti-URL attack method, phpsession anti-URL
This article describes the PHP anti-URL attack method through the session. Share to everyone for your reference. The implementation method is as follows:
Through the session tracking, it is easy to avoid th
validation, but you can also insert a server-side method call. If you can't find a ready-made validation object, you can create one yourself by CustomValidator.
⑸ the user login name, password and other data encryption to save.
Encrypting the data entered by the user and comparing it to the data stored in the database is equivalent to "sanitizing" the data entered by the user, and the data entered by the user no longer has any special meaning to th
number of unusual sign disturbances. For example with SARFU scanExample with the SARFU scan:Hping3-q-n-a 10.0.0.1-sarfu-p--flood 192.168.0.26. Land attackLand attack principle is: with a specially crafted SYN packet, its original address and destination address are set to a certain server address. This will cause the receiving server to send an syn-ack message to its own address, which then sends back an ACK message and creates an empty connection. E
online access to a complete set of free open source software, including secure transport protocols. The platform includes a new Secureshield runtime library that runs in a specific context and manages container partitioning and isolation in a trusted execution environment. like all arc processors, the ARC SEM processor has an ecosystem of reliable software and hardware development tools that support it, including: the Metaware Development Kit for efficient code for deep embedded applications, t

EvilGuard: New Attack method of the Anroid PlatformRecently, we discovered the first Trojan using Process Protection Technology on the Android platform. This trojan executes its own released malicious executable files to protect itself against anti-virus software cleanup. We named this trojan family "EvilGuard ", and exclusively released the demon guardian Trojan killing tool (download) to help users avoid
This article introduces the principle of ARP attack and the network security problem caused by it, in combination with the actual situation, this paper puts forward a multi-level prevention method in the campus network to solve the network security problem caused by ARP attack, and finally introduces some effective methods to detect and defend against
